Just changed the battery on my 2012 CMS All4. The PRND indicator on the tach quit showing what gear it is in, and the cruise control will not turn on. I replaced the battery after getting the warning of excessive battery discharging. I have access to a SnapOn Ethos Edge and performed the battery registration. Any thoughts or ideas? We have had -10 to +10 degree weather for the last week. Don't know if the temperature affects this at all. Car runs perfectly otherwise.

Thanks

 

The Snapon scanner should be able to read fault codes in the instrument cluster. Start there.
